Part a

If today is Friday, then 7 days from now is also Friday. Same goes for 14 days, and 21 days.

We have 25-21 = 4 days left over. Adding 4 days to Friday leads to Tuesday

Notice how 25/7 = 3 remainder 4. That "remainder 4" bit is directly connected to adding those 4 days.

Answer: Tuesday
==========================================================
Part b

32/7 = 4.57 approximately
32 = 28+4
32 = 4*7+4
32 = 4*7+4
32/7 = 4 remainder 4

Focus only on the remainder
We will be subtracting 4 days from Friday since we are rewinding into the past this time.

Friday minus 4 days lands on Monday.

Answer: Monday
